Tried everything, factory reset, set up with and without sensors, router, smartphone, sensors and station right next to eachother. Put way too many hours into this and prefer not to waste the cost of the station and 4 sensors. Help!
I'm having the same / a simular issue of temperature related readings, but at a different temperature level (for me it must be > 14 degree). I massure the dew point as well (temperature = orange, dew point = yellow). It looks to be more related to water in the air than only to temperature.
@zboblamont have you been finally been able to find a solution?
Update and problem fixed!
For everybody that will encouter this, the problem was at the sensor side because of the folder of the sensor! We created some metal brackets for it and they where exactly the same diameter. The fact that the mount squeezed the sensor made it return the lowest value.
Just needed to adjust the hole and everything was ok!
https://github.com/mysensors/MySensors/pull/1562 switches to using libgpiod instead of the earlier interface. I have not tested it myself but it looks good.
FYI, I have found my error
The description of my setup was not totally correct, I don't use an arduino but a atmega328p standalone.
The root cause was the use of the internal oscillator, it is not enough accurate. I am now using an external quarz and it is working fine
@Eme
Thank you for coming back to report how you solved your problem! Your comments will help other people.
I am a big fan of Frugal Tech and I think MySensors is great for that.
Alas, MySensors is not well supported anymore. Right now I'm having problems linking to the home page It's people like you and me that will keep MySensors going.
Thanks for your help.
